Ugh..., so no weird planetary matter time dilation twist or speedometer reading strangeness. Thanks for your patience Dale.

If the person at the center of the Earth measures the length of day to be slightly less when in reality the length of time that elapsed was the same and his rotations were in sync with the person on the surface wouldn't the person traveling in the car be much like the person in the center of the...

Ok, so you are saying that if I was traveling in a car at .5c and I started counting off mile markers to calculate speed compared to my watch that I would conclude that the speedometer was wrong even though it is correct. Thanks Dale!

No, I see what you are getting at though. Let me put it this way, if you had a string tied between two people, One person remains stationary but rotating in the center and one walks around the person in the center with the string taught doing laps. The person in the center makes one rotation...

Without rotation, obviously there would be no twist. My whole question has to do with the rotation plus time dilation. Thanks.

Thanks George, but your "low level of mathematical rigor" is still way above my highest level of mathematical understanding.:smile:

Twisting due to rotation and time rate differences within a single object. How could you view a clock moving at a conflicting rate in the center and not have a "twist". Whether time dilation is caused by gravitational redshift or angular velocities doesn't really matter. Thanks for the replies.

Okay, if what you are saying is true, then is it possible for it to be perceived as twisted but actually not be physically?

Time dilation plus relative movement is what I am saying.

How is that possible with the object spinning? If the spinning is calculated in distance/sec., and the seconds are longer in the center...? Let's say the center clock is slower by 1 second per x amount of years, then it should take the center x years times 86400 to be one rotation behind the...

What is the answer to the hole question? Is the Earth wound like a clockspring inside?

What about time dilation on the surface due to angular velocities within the spinning sphere? (I think I got my terminology right) Does the gravitational redshift make the entire object time neutral? Sorry, I meant to ask this first.

Thanks Dale. So if you drilled a hole to observe it, wouldn't that hole at some point become twisted sort of like a yoyo string?

What would a clock do at the center of the Earth compared to a clock on the surface and why?

Sorry, I know that the speed of light cannot be reached by anything with mass. I wasn't talking about a rapidly spinning rod though, just one spinning for a long period of time. This is where i was pointed to understand warped spacetime due to angular velocities...
